What is the unit saying? What is the serial #?The serial# is on a white tag on the bottom of the power supply. Forexample, serial number CM3 01 06 13 86 can be read as follows: CM3means it is a ClorMatic III, 01 is the year, 06 is the month, 13 is theday and 86 is the unit manufactured that day. Is the unit in warranty? Warranty is 2 years from the date ofinstallation. What is displayed on the LCD?If the unit is on don’t turn it off! Which indicator lights are lit (if any)?2

What does the LCD mean?On power up the AquaPure/PureLink unit: ‘50’ or ‘60’ – The unit is detecting the electrical supply to optimize the unitsettings. 60 cycle power is the US standard. 50 cycle power is common inEurope (note: if the unit detects 60 cycle electric supply then it will default todegrees F for the pool temperature reading). ‘Chlorine Production’ – displays current % production rate for chlorine ‘Wait’ – the unit is still testing its diagnostics ‘No Flow’ – the unit does not detect enough water flow ‘Flow’ – flow sensor is indicating to the unit that it has enough water flow5

What does the LCD mean? ‘LO’ – indicates that the water temperature is less than 51 deg. F ‘BO’ – indicates the boost cycle which can be activated by pressing the ‘PoolTemperature’ key for 10 seconds; it can be cancelled by holding the same keyfor 10 seconds. ‘EC’ - indicates the unit is being controlled by an external controller or ORPdevice. ‘JA’ – Indicates operation is controlled by a Jandy AquaLink RS or PDA, andsystem is in AUTO MODE. ‘JO’ – Indicates operation is controlled by a Jandy AquaLink RS or PDA, andsystem is in SERVICE or TIME MODE. ‘JB’ – Indicates operation is controlled by a Jandy AquaLink RS or PDA, andsystem is in BOOST MODE.6

What do the indicator lights mean? ‘Cell On’ – Full power is being applied to the cell, and making chlorine ‘Cell Resting’ – The cell is in the off portion of the chlorine production cycle ‘Flow’ – Water flow is present ‘Cell Reversing’ – Automatic cell cleaning cycle in progress ‘Add Salt’– Salinity is 2.5 grams/liter or less. Should be 3.0 – 3.5 grams/liter ‘Service’ – Read the service code and refer to the manual ‘Power On’ – Power is turned on and reaching the front board7

What do the other keys mean?Chlorine Production Rate The arrow up button (‘B’) increases the % chlorine production The arrow down button (‘A’) decreases the % chlorine production ‘Pool Temperature’ (‘D’) will give the water temperature in eitherdegrees Fahrenheit or Centigrade Salinity (‘C’) will give the salt reading in grams per liter, this can beconverted to parts per million by removing the decimal point and add 2zeros. Example 2.8 gpl 2800 ppm8

Visual check - flow sensor/cell Check the cell, flow/salinity sensor and power supply for damage Ensure that there is water flow through the cell and that the flow sensoris plumbed in the proper position below the pipe so that it can’t trap airor gas (hazardous) against the sensor.Flow/Temp/Salinity SensorFlow/Temp/Salinity SensorPreferredPlumbingWater FlowHazardousPlumbingWater Flow9

Visual check for installation & damage Be sure that the cell positioned properly and the DC cord is connectedproperly to the cell. Check the flow sensor cable and cell cable for damage (chewed on byan animal, weed-wacked, etc.). Look for water leaks at the cell and flow sensor. Examine the cover and overlays to ensure their integrity against theelements Inspect for proper installation of unit. For safety reasons it isIMPORTANT that the unit is wired to turn off/on with the pool pump.The cell is mounted as the last piece of equipment in the return line.10

Inspection of Power Supply Carefully remove the front cover and support it to avoid damaging theconnectors and wires inside. There is a cable which connects the frontand back boards together, which can be easily damaged. Inspect the front and back boards for damage (cable pulled loose, pinsbent in connectors, etc.). Look for burn marks that might indicate anover-heating condition. Inspect the transformer wires at the back board connection to ensurethere isn’t any indication of overheating. Look for indications that water has been in the unit. Check the unit to be sure that it is grounded to a permanent earthground (the common approved earth bonding point).11

TemperatureChange display between Fahrenheit and Celsius Press and hold the ‘Pool Temperature’ (‘D’)key for 15 seconds. The system will beepwhen the button is pushed, it will beep againafter 10 seconds, and again after 15 seconds.Release the key after the third beep. Press ‘Salinity’ (‘C’) key within 5 seconds toenter temperature change screen. The system will display a “1” followed by ‘F’or ‘C’. Press ‘Chlorine Production Rate’ uparrow key ( ‘B’ ) to toggle from F to C. Press ‘Salinity’ (‘C’) key within 5 seconds toplace the change into memory, (the unit willbeep when pressed).12

Salinity CalibrationConditions to check before calibratingThe salinity reading must be compared to a reliable outside source. ( Myron meter, titrationtest, etc.) Minor variations are to be expected.The flow sensor must be cleaned, and checked for damage.If unit has a Rev. 8 front board it must be tested before proceeding.Salt must NOT have been added within the last 24 hours.If a spare flow sensor is available. Connect it to the unit and place it in a bucket of the poolwater to compare readings.Note- The unit must have the power turned off before either the old or new flow sensor canbe installed. Each time a flow sensor is unplugged and plugged back in again the computerinside the unit must be reset by turning the power ‘off’ and then ‘on’. Failure to do this willresult in erroneous readings.13

Salinity Calibration Press the “Salinity” button and hold it until it beeps 3 times. Thesystem will beep when you push it and then at 5 seconds and again at10 seconds. Release the button after the 3rd beep. Press and release the “Temperature “ button within 5 seconds to enterthe salinity calibration screen. The system will display the salinity reading, press the up arrow toincrease the reading and the down arrow to decrease the reading. When the proper reading is reached press the “Temperature” buttonwithin 5 seconds to store it in memory.14

Transformer Voltage on Rev. 2 backboardReading the AC voltage between T.P.-A and T.P.-B will check the transformeroutput voltage. It should be approximately 75 VAC.A75BDCVOFF1000. K2KNPN200PNP15

Current test on front board(Note: - either the ‘Cell On’ or ‘Cell Reversing’ light must be lit during this entire test)Test Cell Current FlowTo test the amperage going across the cell, you need to test the DC millivolts from K to HThe reading should be approximately 120 DC millivolts. 20 millivolts equal 1 ampere on a 1400 unit, 40 millivolts equal 1 ampere on a 700 unit.120DCV1000.

Electrical Test on Front Board.To read the front board AC voltage, test between “A” and “C” on the test strip that is inthe upper left hand corner of the front board. The AC voltage should be around 21 VAC.21DCVOFF1000. K2KNPN200PNP18

Troubleshooting - Front BoardTo help diagnose whether faults are occurring on the front board or with theflow/salinity sensor three new test buttons have been added in the upper corner ofthe front board.They are:– ‘R-Temp’– ‘H-Temp’– ‘Salinity’19

Troubleshooting - Front BoardDisconnect the flow salinity temp sensor from the front board. Press and hold the testbuttons marked salinity and R-temp. While still pressing the test buttons press the ‘Salinity’key (‘C’) on the front cover of the unit. The LCD should read 2.8 gpl*.While still holding the two front board test buttons press the ‘Pool Temperature’ key (‘D’). Itshould read 75 F or 24 C.Next, press and hold the board ‘H-Temp’ test button, and at the same time press the ‘Salinity’key (‘C’) together with the ‘Chlorine Production Rate’ arrow down key (‘A’) on the frontcover of the unit. The LCD should read 91 F or 33 C .If the readings are correct then the front board is O.K. and the problem is with the flow sensor.On the other hand if the readings are different then it indicates that there is a problem with thefront board.When the testing and repair is complete reconnect the flow sensor and reset the internalcomputer (do this by restarting the unit).*Note: If the the salinity reading has been recalibrated this reading maybe different.Before condemning the board check salinity setting.20
